Detective Harrison "Harry" Morgan is a fictional character in the Showtime television series Dexter and the novels by Jeff Lindsay upon which it is based.

[1] Harry Morgan is a detective and highly respected member of the Miami Police Department, and a close friend of his immediate superior Lieutenant Tom Matthews.

Dexter prizes these lessons as a means to satisfy his homicidal urges with his father's approval, dubbing the rules as the "Code of Harry".

Harry's relationship with his biological daughter Debra, meanwhile, is more complicated; she craves her father's approval, but feels that he favors Dexter.

When Juan Ryness, a pimp who murders his own prostitute, is released due to a faulty search warrant, Harry loses his temper and tells Dexter he was right in training him.

Harry finally parts ways with Dexter in the series' penultimate episode, "Monkey in a Box", when Dexter decides to leave serial killer Oliver Saxon (Darri Ingolfsson) for the police and join his son Harrison and girlfriend Hannah McKay (Yvonne Strahovski) at the airport to move to Argentina.
